Biology
Baudier et al. (2015) studied thermal tolerances of a variety of army ant workers. Eciton mexicanum was one of a number of army ant species sampled with a life history that includes both below and above ground activities.
Jack Longino: This species is a montane specialist, occurring in cloud forest habitats. It is common in the Monteverde area, from 1300m on the Pacific side, across the divide, and down to 900m on the Atlantic side. I also have records from Fila Cruces near San Vito, and the 1500m site (Finca Murillo) on the Barva transect. Raiding columns are normally seen during the day, and it may be a primarily diurnal forager.

Description
Queen
Mann (1926) - Length 11.5 mm.
Head from the front about as long as broad, slightly broader in front than at occipital border, sides feebly rounded, occipital border emarginate, occiput and vertex with large impressed areas; vertex and front with a median longitudinal groove that becomes stronger anteriorly and terminates at posterior border of clypeus. Ocelli lacking; eyes of a single, white facet, situated a little behind middle of sides of head. Mandibles slender, thickest at middle, nearly straight, their tips obtusely pointed. Median, triangular portion of clypeus longer than broad, anterior border very feebly emarginate. Frontal carinae anteriorly rather acute above, posteriorly broad and convex. Antennal scapes robust, clavate, about half as long as head; .funiculi more slender than scape, the first joint as broad as long, the others distinctly longer than broad, the terminal slender, connate and nearly as long as the two preceding joints together. Thorax long, very gradually widened from front to rear, in profile about three times as long as deep, slightly rounded in region of pronotum, flat behind, the dorsal surface of mesonotum shallowly, though distinctly impressed at middle. Propleurae shallowly and broadly impressed. Promesonotal suture very indistinctly indicated by an impressed line; mesometanotal suture not discernible. Meta-epinotal impression distinct. Basal portion of epinotum much longer than the flat declivity, into which it broadly rounds; dorsal surface a little broader than long, strongly and broadly impressed at middle, the impression deepest posteriorly, sides behind middle subgibbous. Petiole from above transverse, not as broad as epinotum, sides very feebly divergent behind, anterior corners broadly rounded, posterior corners projecting and obtusely angulate, posterior border strongly emarginate, dorsal surface concave at middle, with rather strong convexities at sides of concave portion, then sloping and indistinctly impressed toward lateral borders; seen from the side the node is much higher than long, arcuate in front and above and emarginate on posterior outline, with the anterior portion of sides convex and the posterior concave. Gaster elongate oval. Hypopygium and pygidium submembraneous at borders, which in the former are nearly straight and in the latter triangularly excised. Sting not visible. Legs rather short, slender. Claws simple.
Gaster shining, the rest nearly opaque. Head, thorax and epinotum densely and finely punctate, the head more shallowly than the rest, and in addition with scattered, coarser punctures most conspicuous on the epinotum. Petiole densely and shallowly punctate and more shining. Gaster with distinct, irregular, separated punctures, each of which bears a moderately long, stiff, finely pointed yellow recumbent hair. Mandibles and anterior border of clypeus sparsely punctate.
Erect hairs yellow, fine and abundant on head, thorax and petiole and appendages.
Dark ferrugineous red, appendages paler, antennae yellowish.
